Last week, XAPPmedia released the 2015 Internet Radio Ad Load Report and there is an entire section on the advertisers themselves. In 2015, the XAPPmedia sample identified 406 distinct advertisers across five leading Internet radio apps. This reflects growth of more than 5x over what we identified in Q4 2014. Leading the pack of these 400-plus advertisers in spot load for 2015 were The Home Depot and GEICO.

XAPPmedia today published the Internet Radio Ad Load Report Q4 2015. Total advertisers identified through 2015 rose to 406, a 5.4x increase over 2014. Average ad load across the five tracked audio publishers rose 5.7% to 2 minutes 29 seconds (2:29). While ad load seems to oscillate around the 2.5-minute mark each quarter, the total advertiser count continually rises.

The Internet Radio Ad Load Report for Q3 2015 showed a small growth in advertisers, but a reduction in the frequency of the top advertisers. The spots are getting spread around among more advertisers. In Q3, Retail and the combined Media, Entertainment & Gaming (MEG) group were again the top two industries represented in Internet radio ads.

On Thursday, we published the Internet Radio Ad Load Report for Q3 2015. A metric we have collected since our first ad load report is Time To First Ad (TTFA). TTFA identifies how much content is delivered to a listener before they receive the first ad.

The best word to describe the Internet radio and streaming advertising landscape in Q3 2015 is dynamic. As Q3 progressed almost all eyes were on Apple Music’s 11-15 million trial users and the “will they” or “won’t they” subscribe question. Advertisers seemed to be the one group not to care.

The Q2 Internet Radio Ad Load Report recorded that advertisers grew 26% over the first quarter of 2015. While the rise in the numbers of advertisers occurred broadly across industries, the automotive and education segments led the growth.

One of the headlines from the Q2 Internet Radio Ad Load Report was continued growth in the number of advertisers identified. More advertisers indicate broader interest in Internet radio as an advertising channel. However, the growth in advertiser diversity is not developing equally across publishers. Two publishers have expanded their advertising base significantly while three others have not.

XAPPmedia today released the Internet Radio Ad Load Report for Q2 2015 and the data show that both the ad load and number of advertisers rose over the previous quarter. It also shows that Taco Bell, GEICO and NAPA had the heaviest spot rotation during the quarter.

The Internet Radio Ad Load Report for Q1 2015 presented some interesting numbers on a declining ad load. However, the more intriguing finding was the steady growth in advertisers identified across industries. We admitted surprise to the large number of advertisers we identified in the Holiday 2014 Internet Radio Ad Load Report. In the first quarter of 2015, we were surprised again.
